List....I have read the diatribe on this extra mechanical devise that many are using to be able to continue to tune pianos, with great concern. If you are experiencing pain in you striking arm it is suggesting that you are either tuning too many pianos a day/week or ....most likely....applying a striking blow far in excess of the required downweight needed. I also would like to add that a very big percentage of customers would be horrified when they see you apply this closed fist assault on their prize instrument with a Whakker/thumper etc. Most of these customers would be too polite to say anything, but their minds must be in a turmoil over whether they should ask you to be less aggressive with their beloved piano. I would suggest that if you are tuning too many pianos a day/week....have a break and let the injury heal or.... have a close look at your technique and adjust accordingly. I tune 25-30 pianos a week and I hit very hard... but the only injuries I have at the end of the week are tender finger tips. Concert Pianists practice 8 hrs and more a day.......How many of them use...... Key Whakker/Thumpers?.....think about it!! Robin (Aussie)
